Interface definition for a listener that's invoked when a drag event is dispatched to this view. The listener is invoked before the view's own onDragEvent(android.view.DragEvent) method. To fall back to the view's onDragEvent(DragEvent) behavior, return false from the listener method.
true if the drag event was handled successfully; false, if the drag event was not handled. Note: A false return value triggers the view's onDragEvent(android.view.DragEvent) handler.
